Companies are handing every employee AI coding tools and calling themselves AI-native — then blocking everything those employees build. Yakko Majuri, early PostHog engineer and infrastructure lead at Doublepoint through its acquisition by Oura, just launched Railcode: a secure home for internal apps and AI agents where you build with your own tools and deploy in seconds. He gives a live demo — Railcode's first on camera — and explains why most software going forward will be internal.
Topics covered:
- The "AI-forward" illusion: giving out Claude Code isn't a strategy
- The one-question test: are you holding your team back?
- Why most software is about to go internal (and when internal tooling IS the product)
- The CEO who vibe codes vs. the CTO who wouldn't let him ship
- Joining early PostHog through the handbook: work trials, six-person teams, hackathons
- Finding your startup idea by pulling the thread through your old customer notes
- Advice for solo founders: build the thing that's an extension of you
Guest: Yakko Majuri — founder of Railcode (railcode.dev), early PostHog engineer, Solo Founders Program member.
